Hi everyone, my last A1C was 6.2, yay! Still going through multi injections daily with insulin pens. I also have the CGM G4 as a way to avoid lows. My CDE wants me to consider the newest medtronic device, which is a pump/sensor all in one. I THINK it's considered the latest and closest device to an artificial pancreas, please don't quote me on this! This is why I am asking any experiences or knowledge about this would be great!

I don't have a Medtronic pump, I don't have a pump at all. I do have a Medtronic pacemaker and it is perfect! Accurate readings and a LONG battery life.

Congratulations! It's amazing what is available now. It appears you got some good information from these wonderful members. I've learned so much from others here…Tony5657 in New Braunfels, TX

Hi Tony, thanks, it is amazing what is out there, what I find very disturbing is that your access to these devices varies on your insurance coverage, we should all have the right to only the best tools when it comes to taking care of ourselves.

Medtronic is a very trusted company. My husband has an internal medtronic pump in his abdomen that administers medicine directly to his spine. He's had it for 16 years (3 actual ones, as they last about 5 years) It is a life saver for him and I knew they were working on something for diabetes. Sounds great. Do you have a link to any information on it that you can share?

Hi Gabby, I do have a link and other information provided by CDE. I value the responses of my friends, here on DC, like you!!!!! Best wishes, thanks

Nice work on your A1C, its fairly hard to get there. As far as the new medtronic device, see if you can find people on the blogs that are similar to your age, body size and other numbers such as cholesterol, lipids…They will most likely be able to give you an accurate judgement if the new device might work for you. But keep in mind, you are successful with the CGM G4, and you might not want to mess with success.

Congratulations on the 6.2! WTG! We all know how you must have worked for that! But for me I have friends using the pump, and I think of it the same way. But have no other knowledge! Good Luck! Would love to know what you find out!

If you have the Dexcom CGM with the G4 sensor, I advise you to stick with it. Many people do have success with the Medtronic pump with the Enlite sensor, but then many people have poor results with it. I had much better results with Dexcom, but can no longer use a CGM because my new insurance does not cover CGMs. I wore my Dexcom and my Metronics pump separately as two different devices. They did not communicate with each other, but the accuracy with the Dexcom,for me, was much better than the Medtronics CGM. You can go to the website and find a Dexcom Users group that has more than a thousand members. They give high praises to the Dexcom G4, and you can get a lot of good help there.

Hi Richard, thank you, this helps me. My resistance to the pump has been because I am on a very low dosage of insulin and sticking myself has never been a problem. This helps me.

You're talking about the new Medtronic Minimed 530G system with Enlite. The CGM which is still attached separately, directly communicates with the pump and it has a feature to temporarily suspend the basal delivery if your CGM detects your BG is falling to a pre-set low-level for you. (The "Threshold suspend" feature.) It's one step closer to a true artificial pancreas. I've only read good feedback about it on Medtronic Facebook and the Medtronic Minimed Ambassadors Group on Facebook. Medtronic also has a YouTube channel; I am currently using a Medtronic Minimed Revel Pump and do not use a CGM but may explore an upgrade to the new Minimed 530G. Great A1c, BTW!

Thanks Lou, it's a hard decision, that's why I wanted input from what I consider the most reliable sources. Kind of like a research study, if you want to all it! Hope you're well!

Type1Lou 2014-02-22 17:37:42 -0600 Report

Thanks for asking…I'm doing well. I noted your comment to Richard about your low insulin dosage. I am highly sensitive to insulin (sensitivity factor 0f 120) and, prior to pumping, I averaged around 21 units per day of total insulin (Lantus and Novolog). Since beginning pumping in 2011, my daily insulin use now runs between 16 and 18 units of Novolog or Humalog per day…so, I too, do not use a great deal of insulin. That said, I'm kicking myself for having waited so long to try a pump. Dosages can be finessed to one one hundreth of a unit…something that injections can't achieve. Your basal insulin needs can be tailored to your metabolism. I have 3 basal settings for my pump depending on time of day. They run from .10 unit per hour to .525 unit per hour. I didn't have that option with Lantus. I can also either increase or decrease my basal insulin delivery if I feel it is needed. When I exercise, I'll suspend my basal delivery 30 minutes prior to and during the exercise…again, not something I could do with Lantus…once you take the shot, it's in your system! There are many good pumps out there but I think the Medtronic 530G with Enlite is one of the few, if not the only one, where the CGM communicates directly with the pump. The March issue of "Diabetes Forecast" has an interesting article about artificial pancreases and discusses some research prototypes. The article is titled "Building a Better Pancreas". It sounds truly promising. According to Medtronic literature, The "Minimed 530G with Enlite is the first product approved in a new FDA category: OZO: Artificial Pancreas Device System, Threshold Suspend." I don't know if others have also been approved. I don't think you'll be disappointed with a pump.

Lou I did meet one of the nurses at my Enodo's office who is on the medtronic, 530 G with Enlite, T1 for 30 years, she says she loves it! She only uses the sensor at night, for lows, she loves all the features it comes with! She highly recommended it! Will let you know what I decide. How did you figure out your sensitivity factor? Would love to learn more about this.

Type1Lou 2014-02-23 10:43:31 -0600 Report

Actually, when I started pumping, the endo calculated my insulin sensitivity which is a setting for the pump. Gary Scheiner, in his book "Think Like a Pancreas" provides a chart and formula for how that is calculated. He states "Figure your average total daily insulin, including basal and bolus, ..then divide it into both 1500 and 1800. The result is an approximate range (in mg/dl) of how much one unit of insulin will lower your blood sugar. There is more than one way to calculate sensitivity but he favors this one.

Thanks, actually it's on my list to order this book also recommended by my Endo. Now I will have to do that soon! Best wishes!

Hello there, you must be a type one diabetic. I am type 2 and not on insulin or any meds at all. If you are type 2 let me know, have a great book to share with you. Take care and good work on the 6.2, obviously this is a big improvement for you.
